force use of pandoc version >= 3.1.12.2

Browse Source 
The `bin/pandoc-wrapper.sh` tool will verify that the ssytem
has a recent enough version of `pandoc(1)`.

We explain why we insist on `pandoc(1)`. version >= 3.1.12.2
in comments where the $PANDOC_MIN_VERSION is set.

Added `--wrap=preserve` as a default argument to `pandoc(1)`.
While this change will impact every HTML file generated,
we believe this will improve the ability of someone to look
at the generated HTML and correlate with the original markdown.

Changed `bin/pandoc-wrapper.sh` VERSION from "1.4.2 2024-03-17"
to "1.4.3 2024-03-18".

Performed `make www` to achieve all of the above and to generate
HTML using the new  `--wrap=preserve` `pandoc(1)` mode.

<h3 id="usage">Usage</h3>
<p>This program divides the image into a specified number of rectangles.
This process is content aware, so the algorithm tries to match most of
the information. However, it doesn’t find the best theoretically
possible layout.</p>

<p>Made this thing while experimenting with the idea of representing an image with
rectangles (lossy compression). It’s not very good in that sense, but the
results look funny, like a kind of cubism pixel art.</p>
<p>Do not use values above 50000, it’ll be slow.</p>
<p>To understand how this works, just try running with 1,2,3,4… number
of rectangles. At each iteration, the rectangle with the biggest
difference from the picture data is split (halves may have different
size) horizontally or vertically to get the minimum difference.</p>

ImageMagick). For instance after running the command suggested by the
judges:</p>
